Title: Method of generating pulsed neutron beams
IPC: H05H3/06
Filed: 1962-12-05
Abstract: 976,770. Heavy-ion-beam tubes. TOKYO SHIBAURA ELECTRIC CO. Ltd. Dec. 5, 1962 [Dec. 5, 1961], No. 45921/62. Heading H1D. Apparatus for producing a pulsed neutron beam of narrow-width pulses from a tritium target 5 comprises a deuteron ion source 1, from which an ion beam is generated by impressing an ejecting voltage across a probe 2 and a canal 3 contained in the source, an accelerating tube 4 for the ion beam, deflector electrodes 6, and a slit 7 through which the ion beam can pass to bombard the target 5. The ion beam is pulsed, so that it has the form shown in Fig. 2b, by pulsing the ejecting voltage applied across the elements 2, 3. The deflecting voltage applied to the electrodes 6 is also pulsed, the timing being such that part of an ion pulse, when it reaches the electrodes 6, is allowed to pass through the slit 7 whilst part is deflected. The pulsed ion beam which reaches the target 5 is thus constituted by the narrow width pulses B5 shown in Fig. 2 (c), and these pulses B5, imping- ing on the target 5, generate a pulsed neutron beam having the same configuration.

Title: Improvements in or relating to alumina monohydrate
IPC: C01F7/447
Filed: 1961-12-29
Abstract: In a process for the production of an alumina monohydrate-containing composition wherein there is formed an aqueous slurry of an alumina hydrogel which is wholly or predominantly in the monohydrate form, the alumina monohydrate is stabilized against conversion to other forms of alumina by contacting the alumina hydrogel slurry at a pH greater than 7 with a chelating agent containing polycarboxylate ions.  The alumina hydrogel may be formed by hydrolysing an aluminium alcoholate, or by admixture of an inorganic base and an aluminium salt of an inorganic acid.  The chelating agent comprising e.g. 0.5-3% by weight of the alumina in the slurry, may be added together with, or after, the precipitant employed to precipitate the alumina hydrogel from aqueous solution.  Specified chelating agents are polycarboxylic acids containing 2 to 10 carbon atoms and salts thereof, e.g. ammonium citrate oxalate and tartrate.  Alumina gel containing a stabilized amount of trihydrate may be obtained by adding to the monohydrate gel an amount of chelating agent insufficient for complete prevention of ageing. The stabilized alumina hydrogels may form the precursor of calcined alumina-based catalysts (Division B1).ALSO:A platinum-alumina catalyst is made by adding chloroplatinic acid and hydrogen sulphide or platinum sulphide sol to an aqueous slurry of alumina hydrogel in which the alumina, wholly or predominantly in monohydrate form, has been stabilized by contact with a polycarboxylic compound at pH greater than 7.  The composition may be dried, calcined at 800-1200  DEG F. and reduced by hydrogen at 800-1100  DEG F.  The catalyst may contain 0,1-1,5% by weight of platinum, or a platinum-group metal, and may also include chromium and molybdenum oxides.  Catalysts having surface areas of 418 sq.m./gm. are referred to.

Title: Article shingling apparatus
IPC: B65H3/56
Filed: 1970-10-06
Abstract: 1316328 Feeding sheets XEROX CORP 6 Oct 1970 [8 Oct 1969] 47466/70 Heading B8R In apparatus for feeding flat articles, e.g. newspapers, one by one from a pile to a machine such as an addressing machine, the pile is moved forward on a band conveyer 26 to devices which separate the bottom articles and move them forward in shingled formation, and means are provided to prevent the upper articles of the pile from toppling off the pile when a pile of too great a height is used. The shingling devices comprise two spaced apart and adjustable shingling gates 35 and a control roller 37 between the gates, which roller rests by its own weight on the articles. An arm 55 depending from and pivoted on a spindle 50 is urged by a spring into the vertical position shown against a stop 78. Another arm 58 is fixed at one end to the arm 58 and at its other end is adjustably pivoted at 63 to a member 62 having an inturned end part 68. A link 71 extends from a pin 71 on the member 62 to a pin 73 adjustable on a fixed arm 75. As the pile is moved forward by the conveyer it tilts the arm 55 until the latter is parallel with the gates 35 so that shingling takes place. At the same time the arm 58 causes the member 62 to be moved behind the top of the pile to prevent the top articles from sliding off the pile. The arm 55 reverts to its vertical position when only a few articles of the pile remain, and the parts 58, 62, 68 resume the position shown. At this point, a switch 25 adjacent to the conveyer 26 causes operation of a supply conveyer 20 to feed a new pile 12 to the conveyer 26.

Abstract: 1,241,334. Short-circuit protection of invertors; control of A.C. motors. LICENTIA PATENT-VERWALTUNGS G.m.b.H. 8 Oct., 1968 [30 Oct., 1967], No. 47708/68. Headings H2F, H2J and H2K. By-pass thyristors T 1 , T 2  (Fig. 1) are provided to prevent damage, under fault conditions, to thyristors 1 to 6 of an inverter supplying a 3 phase load M. Assuming a fault wherein thyristors 1 and 4 are undesirably caused to conduct concurrently, a short-circuit current will flow from the D.C. input to the inverter, through a low resistance path including the thyristors 1, 4 and an interconnecting inductor L; also current will flow from smoothing capacitors C through this path. Thyristors T 1  in series with a resistor r is therefore switched on by a control circuit S t , to shunt the D.C. input and divert current from the inverter thyristors 1 and 4; then after an interval T 2  is turned on and provides a current path directly across the D.C. input. The discharge current of the capacitors, when 1 and 4 conduct, may be used to initiate the firing of T 1 , being sensed by current transformers connected to the control circuit. If the load M is a motor, then a reverse excess current may flow therefrom through reverse current diodes of the inverter and could damage the same. This is prevented by switching on thyristors 7 to 10 across the motor terminals. Due to the by-pass valve form of D.C. short-circuit protection, the current rating of the inverter thyristors may be increased if forced cooling is used. Each thyristor 1 to 6 may be replaced by four thyristors and a commutating capacitor as shown Fig. 2, two diagonally opposite thyristors only conducting at a time.

Abstract: 1315767 Filling containers; feeding articles singly H STRUERS CHEMISKE LABORATORIUM 15 Oct 1971 [16 Oct 1970 29 March 1971] 48039/71 Headings B8C and B8S Apparatus for filling a container 23 having a lid comprises a hopper 4, a conveyer for conveying closed containers singly from the hopper into a filling station, means for opening the containers and means for introducing material into the open containers, the conveyer being reciprocable longitudinally under the hopper between a first position in which it supports the closed and empty container and a second position in which the lid is supported above the empty container at the filling station. As shown lidded dishes 23 supported on two plates 26 forming the bottom of the hopper 4 projecting into a sterile chamber 3, are fed one at a time on to the conveyer 11, by a pawl 27 on a platform forming part of a frame 22 carried by the conveyer and extending into the chamber 3. As the conveyer moves to the left in Fig. 2, the lid of the container passes above two hooks 30 and the dish slides off the plates 26 on to a platform 31, with the lid supported partly by the leading edge of the dish and partly by the hooks 30. When the conveyer has reached its left hand end position, Fig. 8, the lid has slid off the hooks 30 and is in position on the dish. As the conveyer returns to the right hand end position, the dish and lid are detained by the hooks 30, the platform 31 is withdrawn from under the dish which then drops between rails 32, Figs. 10 and 11, on to two lower rails 33, the lid being retained by the rails 32. When the conveyer is again moved to the left, the lid is pushed forward by projections 35 on the platform 31 and the dish is moved forward by a surface 36 on the frame 22 of the conveyer 11, to operate a switch 18 to stop the conveyer while the dish is filled through a tube 21, Fig. 1. Thereafter the dish is pushed further to the left, the lid slides off the rails 32 and drops on to the dish and the closed and filled dish is pushed out of the chamber 3 by a pawl 39 as the conveyer next moves to the left-hand position. An ultra-violet lamp extends through a hole in the chamber 3 to maintain the chamber sterile. In another arrangement, Figs. 12, 13 (not shown), lugs (34), Fig. 4 (not shown), on rails 32 are omitted and a movable bar (45) is provided with a hook (46) which engages the trailing end of the lid as it passes on to the rails (32) and dispenses with the hooks 30. In another arrangement, Fig. 14, 15 (not shown), one side wall of the chamber 3 is adjustable to dimensions of the dishes being processed.
